How are you building your RingWorlds?
This is how I would build them:
First, design a StarBase with the Maximum Amount of Hyper Plasma Bolt V's. This Starbase will cost you:
6.5Kt, 50Kt, 1Kt
A turn before it finishes, alter the queue to build instead the Plating, Cabling or RingWorld Generator Starbases. It looks like this method should save quite a few resources. A very rough estimate might place the savings between 400,000 to 450,000 minerals and radioactives. Of course, this assumes that you have organic production to spare.
Oh, and Geoschmo, I assume you mean propulsion expert?
